THREAD-GUIDE COLLAR.

SPECIFICATION forming part of Letters Patent No. 733,345, dated July 7,1903.

Application filed December 4, 1902. Serial No. l33l9l (N m d l To (tZZwhom it may concern.-

Be it known that 1, WILLIAM E. SULLIVAN, a citizen of the United States,residing at Fitchburg, in the county otWorcester and State ofMassachusetts, have invented certain new and useful Improvements inThread- Guide Collars; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention is an improved thread-guide collar for threading machines,especially adapted for use in connection with threading-machines knownas long chain-quilling machines; and it consists in the peculiarconstruction and combination of devices hereinafter fully described andclaimed.

The object of my invention is to combine with a thread-guide collar anarm or plurality of arms having guide-eyes for the threads, which armsare adapted to be adjusted both vertically and horizontally to take upthe slack of the thread and give the same the required tension toprevent doubling, thus obviating the loss and inconvenience sometimesresulting from doubling and avoiding the necessity of unwinding andrewinding when the same occurs. Y

In the accompanying drawings, Figure 1 is a perspective view of myimproved threadguide collar, showing the same on the rod of athreading-machine. Fig. 2 is a top plan View of the same. Fig. 3 is anelevation of the same. Fig. ais an elevation showing the relativearrangement of my thread-guide de vice and the bobbins on athreading-machine.

In the embodiment of my invention I provide a guide-collar 1, which iscylindrical in form and which is here shown as adapted to be secured andadjusted on the rod A of a threading-machine with alongitudinally-disposed flange or rib 2 on its outer side, which flangeorrib is provided with a pair of vertical 0penings 3, in which aredisposed the vertical portions 1 of the thread-guide arms 5, the latterhaving horizontal arms 6 at their lower ends provided at their outerends with the eyes '7, adapt-ed to be engaged by the threads or yarns.The vertical portions of the thread-guide arms are vertically adjustablein the said openings and are also adapted to. be turned therein, so thatthe said thread-guide arms may be adjustable both vertically andhorizontally, as may be required. The guide-eyes keep the yarns orthreads apart, and as they are drawn and kept at all times under tensionby the revolution of the bobbins doubling of the yarn or thread iseffectually prevented. The vertical portions of the threadguide arms areengaged and secured at any desired adjustment by set-screws 9, whichoperate in threaded openings with which the rib or flange 2 of thecollar is provided. The collar is secured on the rod A by a set-screw12.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A thread-guide collar having a lateral rib or flange provided with avertical opening, in combination with athread-guide arm having avertical portion engaging and vertically adjustable in and also adaptedto be turned in said opening, and means to engage said vertical portionof the thread-guide arm to secure the same at any desired adjustment,substantially as described.

2. A thread-guide collar having a lateral rib or flange provided withvertical openings in combination with a pair of thread-guide arms, eachhaving a vertical portion, a horizontal portion, and a thread-guide eyeat the outer end of the latter, said vertical portions of saidguide-arms being Vertically adjustkil able in the openings in the rib orflange of l my hand in presence of two subscribing Witsaid collar andalso adapted to be turned therein to adjust the thread-guide eyes ofsaid arms from or toward each other, and means to secure saidthread-guide arms when adjusted, substantially as described.

In testimony whereof I have hereunto set DQSSBS.

WILLIAM E. SULLIVAN.
